DNA is a blueprint for each of our identities. The way our genes are expressed affects how our bodies function, what we look like, and who we are, in general. Learn how this important and complex molecule functions.

1) Students will learn what DNA is and they will become familiar with its structure.
2) Students will understand the function of DNA in the human body during the replication of cells, during the formation of new reproductive cells, and in the synthesis of proteins for gene expression.
3) Students will learn about some of the practical applications of genetic engineering.

"Viewers without some prior knowledge about the field of DNA research would find it difficult to absorb the wealth of information this video delivers. Over 25 scientific, and rather technical terms are thoroughly defined both in the script and with clear titles onscreen. Crisp, colorful graphics, both still and animated, and several film clips of microscopic views of molecules enhance the explanation of DNA functions and the replication process. Transitions are delineated by revolving titles and a cleverly chosen slot machine sound effect. Many different ethnic groups are represented in the examples provided. Topics covered include: how DNA information is used, how it functions, what it constitutes and tries to predict, and the direction genetic engineering might take in the future. Both the transcription and the translation of RNA are covered. RNA and DNA are contrasted. Assuming students have some familiarity with the subject of DNA, this could serve as an introductory overview or as a review of the material."SOURCE: School Library Journal, March 2001 IssueAUTHOR: Janet Musil, Sandburg High School, Orland Park, ILReproduced, with permission from School Library Journal Copyright �By Cahners Business InformationA Division of Reed Elsevier Inc.
